There were many things on display at the world fair in Seattle including the Alaska-Yukon-Pacific Exhibition in 1909. On the Pay Streak boardwalk there were numerous human exhibits. 

They actually brought down a group of Eskimos for fairgoers to observe. They also brought 50 Igorot people from the Philippines and made grass huts for them. They basically set up a little village for the Igorot people while fairgoers came to gawk at them. Fairgoers paid an extra 50 cents to see each human exhibit. 

Even more astonishing was one of the raffle prizes. One day during the fair, they had a number of raffle prizes. There was a one month old orphan named Ernest that was a raffle prize. He was “property of the Washington Children’s Home and Society,” according to the Seattle newspaper at the time. 

No one knows what happened to little Ernest after the fair. Incubators were new at the time and they were showcasing them at the fair, too. Instead of being simple and just showcasing the incubators, they had premature babies inside of them for fairgoers to get the full effect of what they could do.
